- Steep Slope Matrix



HydraCM Steep Slope Matrix scored 99.7% effective in reducing soil erosion under AASHTO’s NTPEP testing. It’s designed for medium-length, moderate to steep slope gradients of 4:1 to 1:1 (H:V). HydraCM HECP is a superior alternative to single-net erosion control blankets for controlling erosion and establishing vegetation on steep, challenging slopes. The HydraCM Steep Slope Matrix shall be a hydraulically-applied mulch composed of a patent-pending blend of mechanically processed straw fibers, reclaimed cotton plant materials, performance-enhancing tackifiers, and other proprietary additives. The HydraCM matrix is designed for soil erosion protection, and establishes an intimate bond upon application with the soil’s surface to create a continuous, porous, absorbent, and flexible erosion control matrix that allows for rapid germination and accelerated plant growth.

The all natural fiber mulch shall satisfy the control performance criteria set forth in the Ceriodaphnia dubia, Daphnia magna and Pimephales promelas tests as described in EPA documentation (USEPA 2002) and the Region VIII Whole Effluent Toxics Control Program (EPA Region VIII 1997); therefore illustrating no significant toxicity for the mulch.

Composition: All components of the HydraCM matrix shall be pre-packaged by the Manufacturer to assure material performance and in compliance with the following values. Under no circumstances will field mixing of additives or components be accepted.

HydraMax Systems’ HECPs also:

  • Feature a porous matrix with strong soil adhesion that forms an excellent vegetation establishment and erosion control medium
  • Can be installed up to three times faster than erosion control blankets with one-third of the manpower
  • Have low water-to-mulch ratios that increase productivity by requiring fewer tank loads per site
  • Grow grass quickly with increased germination and biomass production over bare soil

Bags are filled with 50 lbs (23 kg) of material and packaged in a UV and weather-resistant bag. Each pallet contains 40 bags or one ton of material with a plastic cover for enhanced protection from rain and UV rays.
